Solidago

The genus Solidago, or Goldenrod (Solidago), includes about 100 species of herbaceous perennial plants with characteristic yellow inflorescences-baskets typical of compound flowers (like chamomile), sometimes they are collected in more or less elongated panicles. Solidago canadensis is a lush plant up to 180 cm tall. Erect stems are covered with sharp-toothed or almost whole-edged leaves. Yellow small flowers that bloom in summer, in baskets are collected in paniculate or pyramidal large inflorescences, often one-sided. Especially common is the variety 'Golden Wings'. Solidago, or common goldenrod (S. virgaaurea), often called the "golden rod", is a species that is often found in nature. It is characterized by small yellow inflorescences-baskets collected in rare panicles, flowers bloom in July-August. Many hybrids and garden forms (S. x hybrida, or S. x arendsii) with characteristic numerous baskets collected in apical elongated panicles were obtained from crossing Canadian solidago and common goldenrod. Flowers bloom in July-October. Among them, the low-growing (30-40 cm) forms with compact bushes and the weeping form are of particular interest. Also widely known are: 'Golden Gate' with greenish-yellow leaves and baskets gathered in elongated panicles; 'Goldenmose' with green-yellow leaves and baskets in short panicles; 'Crown of Rays' with golden-yellow leaves. shopping carts; "Golden baby" with golden-yellow baskets.

Cultivation

Solidago is grown in the garden in borders and flower beds. Plants quickly develop free space. They are very unpretentious in culture, prefer open places and fertilized moist soil. Although they are perennials, they are often renewed because they quickly absorb nutrients from the soil. In early spring (or autumn), plants are removed from the ground, divided into bushes and planted in soil enriched with organic (20-30 kg/m2) and mineral (3 kg/m2) fertilizers. During the growing season, top dressing is carried out every 3 weeks - fertilizer is added to the water for irrigation in the amount of 15-20 g per bucket. In autumn, the peduncles are cut almost to the root.

Location

Solidago can be planted both in the open sun and in partial shade.

Temperature

Plants are not capricious, resistant to both high and low air temperatures.

Watering

It is always necessary to keep the soil in a slightly moist state, watering often in the spring and summer months.

Reproduction

Propagate by seed and division of rhizomes. The most popular method is dividing the bush, in spring in areas with a cold climate or in autumn in warmer, milder climates.

Diseases

The defeat of young plants by the fungus Elsinoe solidaginis leads to deformation of shoots, slowing down development, and later plants die. Other problems are caused by aster rust (Coleosporium asterum). In both cases, the affected instances are deleted. The small insect Corythuca marmorata mechanically damages the leaves, and the caterpillar Argyrotaenia citrana causes them to curl. Both pests are eliminated by insecticide treatment.

Acquisition

Solidago can be found in well-stocked horticultural centers and specialized nurseries. Check that the leaves have a beautiful intense color.

Solidaster - solidago and Astra From the crossing of plants of the genera Solidago and Aster, Solidaster x was obtained, which inherited the intermediate properties of its "parents". It is a perennial herb with lanceolate to elliptical-lanceolate leaves on long petioles. Baskets are collected in branched paniculate inflorescences. Marginal flowers (located at the edge, which are usually called petals) are bright yellow, brighten over time; tubular (median) - golden yellow. Various garden forms have become widespread, among which those that are used for cutting are especially appreciated, for example, 'Sandor' and 'Santop'. The requirements for cultivation and propagation methods are the same as for solidago.
